安阳沐浴空气能热水器施工电话和你分享螺杆式冷水机的工作原理

    今天电话和你分享螺杆式冷水机的工作原理，如下：

第1.冷水机组的选用应根据冷负荷及用途来考虑。对于低负荷运转工况时间较长的制冷系统，宜选用多机头活塞式压缩机组或螺杆式压缩机组，便于调节和节能。
第2.选用冷水机组时，优先考虑性能系数值较高的机组。根据资料统计，一般冷水机组全年在100%负荷下运行时间约占总运行时间的1/4以下。总运行时间内100%、75%、50%、25%负荷的运行时间比例大致为2.3%、41.5%、46.1%、10.1%。因此，厂家表示在选用冷水机组时应优先考虑效率曲线比较平坦的机型。同时，在设计选用时应考虑冷水机组负荷的调节范围。
多机头螺杆式冷水机组部分负荷性能优良，可根据实际情况选用。
第3.选用冷水机组时，应注意名义工况的条件。冷水机组的实际产冷量与下列因素有关：
a)冷水出水温度和流量；
b)冷却水的进水温度、流量以及污垢系数。
第4.选用冷水机组时，应注意该型号机组的正常工作范围，主要是主电机的电流限值是名义工况下的轴功率的电流值。

第5.安阳沐浴空气能热水器厂提醒在设计选用中应注意：在名义工况流量下，冷水的出口温度不应超过15℃，风冷机组室外干球温度不应超过43℃。

Today, Anyang is a shower of air to water heater construction and you share the screw type cold water machine working principle, as follows:
The selection of the 1 cold water unit should be considered in accordance with the cold load and use. For the refrigeration system with a long working condition of low load, it is advisable to choose the multi head piston compressor unit or the screw type compressor unit to facilitate the adjustment and energy saving.
2 when the water chiller is used, the higher the performance of the system is given. According to the data statistics, the general cold water unit in the year under the 100% load running time of about 1/4 of total running time. Total running time of 75%, 50%, 25%, 100% of the total operating time of the load is approximately 2.3%, 41.5%, 46.1%, 10.1%. Therefore, the shower air can water heater manufacturers said in the selection of cold water unit should give priority to the efficiency curve is relatively flat model. At the same time, it should be considered in the design of the adjustment range of the load of cold water unit.
Multi head screw type cold water unit with good performance, can be selected according to the actual situation.
When selecting the cold water unit, the condition of nominal working condition should be paid attention to. The actual cooling capacity of cold water unit is related to the following factors:
A) cold water outlet temperature and flow;
B) the water inlet temperature, flow rate and fouling coefficient of cooling water.
4 the normal operating range of the model unit should be paid attention to the normal working range of the main motor, the current value of the main motor is the current value of the shaft power under the nominal condition.
5 Anyang shower air can water heater factory reminder in the design selection should pay attention to: in the name of the condition flow, cold water outlet temperature should not exceed 15, air cooling unit outdoor dry bulb temperature should not exceed 43.
Anyang shower air can water heater construction, professional sale of all kinds of air can water heater, ground source heat pump water cooling air conditioning, air cooling machine, food waste processor, water machine, etc., product quality is good, the price is low, after sales have security, is a trusted products, web site: ***
